Technical Field

[0001] This utility model relates to the field of frame bending and forming technology, and in particular to an automated bending and forming equipment for lantern frames. Background Technology

[0002] In the field of lantern making, traditional craftsmanship holds an important position. However, with changing market demands, its limitations are becoming increasingly apparent. Today, the application scenarios for lanterns are constantly expanding, from festival decorations to theme parks and commercial events, leading to higher requirements for both production volume and quality. Simultaneously, the shapes of lantern sets are becoming increasingly complex, demanding higher precision from the frame.

[0003] However, the fixtures used in automated equipment for bending and forming lantern frames have poor compatibility. They can usually only be adapted to lantern frames of specific specifications and shapes. When encountering frames of different sizes or shapes, the fixtures need to be changed, which increases the complexity of operation and production costs.

[0004] Therefore, we have made improvements to this and proposed an automated bending and forming equipment for lantern frames. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the fixtures in the existing automated bending and forming equipment for lantern frames have poor versatility, and the fixtures need to be changed when encountering frames of different sizes or shapes, which increases the difficulty of operation and cost. Therefore, an automated bending and forming equipment for lantern frames is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automated bending and forming equipment for lantern frames includes a workbench, a fixed base fixedly connected to the surface of the workbench, a roller rotatably connected to the surface of the fixed base, and a circular strip extending outward at one end on the surface of the roller.

[0008] The clamping and adjusting mechanism includes a positioning housing fixedly connected to the surface of the worktable and wrapped around the surface of the circular strip, a positioning base fixedly connected to the surface of the positioning housing, a positioning column fixedly connected to the positioning base, a sleeve fixedly connected to the positioning base and located inside the positioning column, a support assembly fixedly connected to the positioning base and located inside the sleeve, and a clamping assembly fixedly connected to one end of the positioning column and located around the support assembly.

[0009] As a preferred technical solution of this application, the support assembly includes a support plate fixedly connected to the positioning base and located inside the sleeve, a spring fixedly connected to the end of the support plate away from the positioning base, a locking pin fixedly connected to one end of the spring and slidably connected to the sleeve, a limit groove being formed at the end of the locking pin away from the spring, and a slider fixedly connected to one end of the locking pin.

[0010] As a preferred technical solution of this application, the clamping assembly includes a wrapping component fixedly connected to the end of the positioning post away from the positioning base, three fixed shafts rotatably connected to the wrapping component and arranged in a circle inside the wrapping component, a fixing block fixedly connected to the surface of the fixed shafts and movably connected at one end to the surface of the limiting groove, and a clamping block fixedly connected to the fixing block.

[0011] As a preferred technical solution of this application, a positioning ball is fixedly connected to the surface of the clamping block, and a fixing plate with one end fixedly connected to the package is slidably connected to the surface of the positioning ball. The surface of the fixing plate is provided with a positioning hole that matches the positioning ball.

[0012] As a preferred technical solution of this application, the surface of the workbench is fixedly connected to two supporting members in symmetrical positions, and a guide roller is rotatably connected between the two supporting members. The surface of the guide roller is provided with the circular strip. The surface of the workbench is fixedly connected to two support columns, and clamping plates are rotatably connected to the surfaces of the two support columns respectively. A vertical plate is fixedly connected to the side of the workbench located on the clamping plate, and an elastic strip is fixedly connected between the vertical plate and the clamping plate.

[0013] As a preferred technical solution of this application, the surface of the workbench is fixedly connected to a mounting base, the surface of the mounting base is fixedly connected to a mounting plate, the surface of the mounting plate is provided with a groove, the surface of the groove is fixedly connected to a telescopic cylinder, the surface of the telescopic cylinder is slidably connected to a telescopic column, a spring II located on the surface of the telescopic column is fixedly connected between the telescopic cylinder and the mounting plate, and a clamping turntable slidably connected to the surface of the round bar is rotatably connected to the surface of the mounting plate.

[0014] Compared with the prior art, this utility model provides an automated bending and forming equipment for lantern frames, which has the following beneficial effects:

[0015] 1. This automated bending and forming equipment for decorative lantern frames, through the cooperation structure of the telescopic locking column and spring in the clamping adjustment mechanism, combined with the clamping assembly with a three-axis fixed axis, achieves active adaptive clamping for frames of various sizes and irregular shapes. When round bars of different specifications enter the clamping range, the locking column drives the slider to slide along the sleeve under the action of spring, so that the three clamping blocks achieve synchronous radial contraction or expansion through fixed axis linkage. This solves the problem of poor adaptability and frequent replacement required by traditional clamps due to fixed size, and significantly improves the versatility of the equipment.

[0016] 2. This automated bending and forming equipment for decorative lantern frames achieves a dynamic self-locking function during the clamping process through the mating structure of positioning balls on the surface of the clamping block and positioning holes on the fixing plate. When the clamping block contacts the frame surface, the positioning balls generate slight rolling friction along the positioning holes of the fixing plate, allowing for flexible fine-tuning while ensuring clamping accuracy. This solves the problem of rigid clamps easily causing damage to the frame surface or clamping offset, ensuring the process stability of bending and forming irregularly shaped frames.

[0017] 3. This automated bending and forming equipment for decorative lantern frames utilizes a composite structure of guide rollers and elastic strips, combined with a telescopic clamping turntable equipped with a second spring, to achieve adaptive adjustment throughout the entire material conveying and forming process. The guide rollers form a flexible support surface through the support components, and the dynamic balance of the clamping plate under the action of the elastic strips ensures stable feeding of round bars of different diameters during bending. The synergistic effect of the telescopic column and the second spring allows the clamping turntable to adapt to the deformation trajectory of the frame in real time, solving the problem of accumulated processing errors caused by the fixed guide structure in traditional equipment and significantly improving the forming accuracy of complex shapes.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0029] Reference Figure 1-5 An automated bending and forming equipment for a lantern frame includes a workbench 100, a fixed base 101 fixedly connected to the surface of the workbench 100, a roller 102 rotatably connected to the surface of the fixed base 101, and a circular strip 103 extending outward at one end on the surface of the roller 102.

[0030] The clamping and adjusting mechanism includes a positioning housing 200 fixedly connected to the surface of the worktable 100 and wrapped around the surface of the round bar 103; a positioning base 201 fixedly connected to the surface of the positioning housing 200; a positioning post 202 fixedly connected to the positioning base 201; a sleeve 204 fixedly connected to the positioning base 201 and located inside the positioning post 202; a support component 218 fixedly connected to the positioning base 201 and located inside the sleeve 204; and a clamping component 209 fixedly connected to one end of the positioning post 202 and located around the support component 218. By setting the nested structure of the positioning housing 200 and the positioning post 202 in the clamping and adjusting mechanism, rapid positioning and clamping of round bars 103 of various sizes can be achieved. During operation, round bars 103 of different diameters are simply inserted into the positioning housing 200, and the center calibration is automatically completed by the cooperation of the sleeve 204 and the support component 218, effectively reducing manual centering errors. It is important to keep the inner wall of the sleeve 204 clean to ensure smooth sliding.

[0031] In a preferred embodiment, based on the above method, the support assembly 218 further includes a support plate 203 fixedly connected to the positioning base 201 and located inside the sleeve 204, a spring 205 fixedly connected to the end of the support plate 203 away from the positioning base 201, a locking pin 206 fixedly connected to one end of the spring 205 and slidably connected to the sleeve 204, a limiting groove 210 formed at the end of the locking pin 206 away from the spring 205, and a slider 207 fixedly connected to one end of the locking pin 206. By setting the elastic linkage structure between the spring 205 and the locking pin 206 in the support assembly 218, dynamic buffer pressure can be provided during clamping. When the round bar 103 is subjected to bending external force, the locking pin 206 adjusts its displacement slightly along the sleeve 204 through the slider 207, and the limiting groove 210 constrains the fixing block 212, avoiding material deformation caused by rigid clamping. During use, it is necessary to periodically check whether the elastic coefficient of the spring 205 has decayed.

[0032] Furthermore, the clamping assembly 209 includes a wrapping component 208 fixedly connected to the end of the positioning post 202 away from the positioning base 201, three fixed shafts 211 rotatably connected to the wrapping component 208 and arranged circumferentially inside the wrapping component 208, a fixing block 212 fixedly connected to the surface of the fixed shafts 211 and movably connected at one end to the surface of the limiting groove 210, and a clamping block 213 fixedly connected to the fixing block 212. By setting the circumferential distribution structure of the three fixed shafts 211 in the clamping assembly 209, a three-point balanced clamping force field can be formed. During installation, it is necessary to ensure that the three fixed shafts 211 are symmetrically distributed at 120° inside the wrapping component 208, so that the clamping block 213 automatically balances the pressure when contacting the irregular skeleton, which is particularly suitable for the stable gripping of polygonal or curved skeletons.

[0033] Furthermore, a positioning ball 214 is fixedly connected to the surface of the clamping block 213, and a fixing plate 215, one end of which is fixedly connected to the package 208, is slidably connected to the surface of the positioning ball 214. The surface of the fixing plate 215 has a positioning hole 216 that matches the positioning ball 214. By setting the sliding engagement between the positioning ball 214 on the surface of the clamping block 213 and the positioning hole 216 on the fixing plate 215, a self-calibration function can be achieved during clamping. When the positioning ball 214 rolls along the positioning hole 216, it automatically compensates for the clamping angle deviation, ensuring that the axis of the round bar 103 coincides with the processing baseline of the equipment during bending. The surface of the positioning ball 214 needs to be lubricated regularly to reduce frictional wear.

[0034] Reference Figure 1 , Figure 7 and 8 Furthermore, the worktable 100 includes two symmetrically positioned support members 300 fixedly connected to its surface. A guide roller 301 is rotatably connected between the two support members 300. A circular strip 103 is provided on the surface of the guide roller 301. Two support columns 303 are fixedly connected to the surface of the worktable 100. Clamping plates 302 are rotatably connected to the surfaces of the two support columns 303 respectively. A vertical plate 304 is fixedly connected to the side of the worktable 100 near the clamping plate 302. An elastic strip 305 is fixedly connected between the vertical plate 304 and the clamping plate 302. By setting up a symmetrically arranged combination structure of support members 300 and guide roller 301, dynamic balance support for the feeding of the circular strip 103 can be achieved. The guide roller 301 forms a flexible support surface between the support members 300, ensuring that circular strips 103 of different diameters are always smoothly conveyed along a preset trajectory during bending. This is particularly suitable for continuous processing of long-sized frames. It is necessary to periodically clean the metal shavings remaining on the surface of the guide roller 301 to prevent slippage. By setting an elastic connection structure between the clamping plate 302 and the elastic strip 305, see Figure 7 It can provide adaptive lateral constraint force during bending operations. The elastic strip 305 forms a bidirectional tensile field through the vertical plate 304, so that the two clamping plates 302 automatically adjust the opening and closing angle according to the change of the diameter of the round strip 103, avoiding the indentation defects caused by traditional rigid claws.

[0035] In a preferred embodiment, based on the above method, a mounting base 400 is fixedly connected to the surface of the workbench 100, a mounting plate 401 is fixedly connected to the surface of the mounting base 400, a telescopic cylinder 403 is fixedly connected to the surface of the mounting plate 401 with a groove 402, a telescopic column 405 is slidably connected to the surface of the telescopic cylinder 403, a second spring 404 is fixedly connected between the telescopic cylinder 403 and the mounting plate 401, and a clamping turntable 406 is rotatably connected to the surface of the round bar 103. By setting a linkage mechanism between the telescopic cylinder 403 and the second spring 404 on the mounting base 400, the constant pressure tracking function of the clamping turntable 406 can be realized. The second spring 404 pushes the telescopic column 405 to keep the clamping turntable 406 always in contact with the surface of the round bar 103, automatically compensating for displacement deviation during bending deformation, and ensuring no risk of detachment during the forming process.

[0036] By setting a rotating connection structure between the clamping turntable 406 and the mounting plate 401, coordinated control of the axial free rotation and radial locking of the round bar 103 can be achieved. The Teflon coating on the turntable surface reduces the coefficient of friction while preventing scratches on the skeleton surface. When bent, the round bar 103 can extend freely along the circumference of the turntable, avoiding stress concentration during torsion.

[0037] Specifically, when this automated bending and forming equipment for lantern frames is in operation: First, the round bar 103 passes through the clamping plate 302, and the elastic bar 305 forms a bidirectional tensile field through the vertical plate 304, so that the two clamping plates 302 automatically adjust the opening and closing angle according to the change of the diameter of the round bar 103, providing adaptive lateral constraint force, avoiding indentation defects, and ensuring that the round bar 103 enters the equipment stably and without damage.

[0038] Next, the round bar 103 reaches the position of the clamping turntable 406. The spring 404 pushes the telescopic column 405, so that the clamping turntable 406 always fits tightly against the surface of the round bar 103. During the bending deformation process, the displacement deviation is automatically compensated to ensure that there is no risk of detachment during the forming process. At the same time, the rotating connection structure between the clamping turntable 406 and the mounting plate 401 realizes the coordinated control of the axial free rotation and radial locking of the round bar 103. The Teflon coating on the surface of the turntable reduces the coefficient of friction and prevents scratches on the skeleton surface. When bending, the round bar 103 can extend freely along the circumference of the turntable to avoid stress concentration during twisting.

[0039] Subsequently, the round bar 103 enters the positioning base 201. The bottom of the positioning base 201 is provided with a through hole 217 to facilitate the round bar 103 to pass through into the clamping block 213. The elastic linkage structure of the spring 205 and the locking post 206 in the support assembly 218 provides dynamic buffer pressure during clamping. When the round bar 103 is subjected to bending external force, the locking post 206 adjusts its displacement along the sleeve 204 through the slider 207, which, together with the limiting groove 210, constrains the fixing block 212 to avoid material deformation caused by rigid clamping. Finally, the round bar 103 passes through the clamping block 213. The circumferential distribution structure of the three fixed axes 211 in the clamping assembly 209 forms a three-point balanced clamping force field. When the round bars 103 of different diameters pass through the clamping space formed by the clamping block 213, their outer diameter difference generates radial extrusion force on the clamping block 213. During the passage of the round bar 103, the extrusion action is transmitted to the fixed block 212 through the clamping block 213. Based on the lever effect, the locking column 206 is driven to move axially along the sleeve 204, causing the elastic mechanism in the support assembly 218 to undergo adaptive deformation. During this stage, the positioning ball 214 rolls and slides along the positioning hole 216 of the fixed plate 215 under the action of the lateral force, correcting the clamping angle deviation in real time. After the round bar 103 has completely passed through the clamping area, the positioning ball 214 slides to the preset position of the positioning hole 216 to form a stable clamping state. After the bending process is completed, the elastic element releases the stored energy, pushes the locking column 206 to reset, and drives the clamping block 213 to return to the initial open state, preparing for the next processing cycle.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
